The German National Library @DNB_Aktuelles AI team just published a paper "Automatic Subject Cataloguing at the German National Library" in LIBER Quarterly (open access):
https://doi.org/10.53377/lq.19422
The paper documents in detail how they use open source tools such as Git, Data Version Control and Annif to implement automatic assignment of DDC classes and GND subject terms to digital publications in various formats. Great work!
@osma @DNB_Aktuelles Interesting how DNB goes straight from the 19th century into the AI world. Their catalogue sucks (with lots of mistakes and lots of bland legacy datasets without much content) because they have implemented zero crowdsourcing features. They skip introducing that and go straight to AI to make the catalogue even worse...
